1 Claim.

This invention is directed to an improvement tor arrangement, there is provided a means in dump wagons, and particularly to the mounting of a rotary hydraulic motor'ln such manner asto insure any desired variation in the speed 5 of raising and lowering the dump body, with the minimum connections between the motor and the dump body, and the adaptability of the motor and connections for disposition to suit any particular body and chassis.

It has heretofore been ,proposed to utilize hydraulic power `for use with dump bodies, but such constructions have involved the use of'a pump for creating the necessary pressure in the hydraulic medium and an elongated cylinder and contained piston for utilizing the pressure of the hydraulic medium for raising and lowering the dump body. This complication requires an expensive independent series of elements, which not only requires constant attention to avoid leakparts, tending after some continued use of the vehicle to collect dirt and refuse in a manner to practically insure unusual wear and breakage.-

Furthermore, such an arrangement, owing to the necessity of a great number of separate parts, presents no selection as to arrangement, and compels the parts to be arranged in practically the same positions without regard to the type of body. 80

hydraulic operation of dump bodies through the use of telescopic cylinders, operated relatively under the'pressure of a hydraulic medium from a driven pump. Here, again, such arrangement requires a specific relative arrangement of parts, permitting no se1ectionand furthermore, a reservoir and pump are necessary and the dumping operation is at best a slow one.

The ideal motor mechanism for a dump body is one in which the motor mechanism presents a small compact unit, capable of being mounted in any position on the chassis, one in which no leakage is possiblejand one in which through adjustment the speed of the dumping operation can be regulated and controlled in accordance with the type of load to be handled. The small age, but compels the use of many supports and It has also been proposed to provide for the` whereby the dump body may be operated rapidly or slowly, as may be required. The provision of a single, small unit presents a clear chassis comparatively speaking, there being no` places for the accumulation of dirt and road refuse during continued use, and a simple wiping of the single part is sufficient to maintain a clean and thereby more effective construction at alltimes.

The invention has therefore for its object the provision of a dump body wherein the diunping operation is carried out through'the useV ofl a comparatively small, rotary, self-contained ino-k tor, adapted to be positioned at any desired point on the chassis, and having simple lower connection with the dump body, which through obvious changefpermits selective variation in speed of operation.

A further object of the invention is the profvision of a motorfcr a dump body lincluding a rotary shaft to be directlysubjected to motor power, and lto be supported in bearings beyond the motor, to thereby materially limitthe direct stress on the motor during dumping operation.

I A further object of the invention is the provision of a motor unit so arranged that it may be supported in transverse frame parts to be re-l movably secured to the chassis frame, with the result of permitting speedy installation and removal when desired.

The invention is illustrated in the accompanying drawings inwhich:

Fig. l is a. side elevation of the improved dump wagon, showing the motor in position and the dump body in elevated position.

Fig. 2 is a similar view, the dump body being shown in lowered or normal position.`

Fig. 3 is a transverse section through the ve hicle chassis and dump body frame, the frame being shown raised and the operating parts being shown in elevation.

Fig. 4 is a plan view of the operating parts, the dump body being omitted, and the lever connections being shown in section.

The invention is directed to that improvement indump wagons in which the motive power for the movement of the dump body is in the form of a hydraulic motor, self contained in that the iiuid used, preferably oil, is contained within the motor body and circulated through means of a pump, with the circulation controlled through xa single valve. This arrangement provides for the securing of a single element on the chassis or frame of the vehicle, presenting a clean neat assembly. which materially simplifies installation andremoval, and entirely avoids any mechanical complication. This unitary arrangement not only simplifies installation and removal', but las the unit is self contained permits the entire motor assembly to be made up, tested, sealed, and completed at the factory, leaving nothing relative to the motor to be connected or provided on the job, and hence relieving the wagon attendant of any correction, connection, or adjustment on the job, and thus preventing the usually inexpert attention usually incident to the liability of other types of hydraulic motors from requiring adjustment or repair in use.

The power unit of the present invention comprises a unit construction I, including a. motor proper, with the motor of the rotary type and mounted in a comparatively small circular casing 2, the width of which is less than its diameter. The motor is of the vane type, with the vane serving to turn a power shaft 3. A pump 4 of the unit arrangement is arranged below and at one side of the motor casing, which pump is driven from the power plant of the vehicle, preferablythe continuously-driven gear of the transmission, .and serves to circulate a motive fluid, preferably oil, to force th vane to turn the power shaft. The unit arrangement includes a valve 5, located below and practically in line with the casing 2, which valve, controlled from the drivers seat, so governs the circulation of the motive fluid as to cause the pump to circulate such fluid for power purposes, or prevent any circulation to hold the dump body in any position of elevation, or permit free interchange circulation within the casing, to permit the dump body to return to normal or lowered position. The power shaft 3 extends in both directions beyond the casing 2, and is terminally provided with lifting arms 1, rigid with though removably secured to the shaft.

The frame bars 8 of the chassis are provided with transverse struts 9, preferably of angle iron, tted between such frame bars, and rigidly secured to such frame bars by brackets I0. Ob-

viously, the securing of this cross frame struc-- ture requires but the forming of appropriate holes in the chassis frame bars for the reception of the bolts for securing the brackets, hence this cross frame may be placed in any position lengthwise the chassis frame bars. Furthermore, the application or removal of this cross frame structure is a simple and expeditiously-effected operation. Extending transverse the cross-frame structure, that is substantially parallel with the chassis frame bars, are spaced motor supports I I. These supports are in the form of angle bars terminally bolted at I2 to the struts 9. Here, again, the obvious and convenient disposition of these motor supports at any desired points lengthwise of the struts, simply by boring holes at the desired points in the struts, provides for any selected placement of the motor.

The motor casing 2 is hung between the motor supports II, being removably connected thereto in any mechanical or suitable manner as indicated at I3. In this position the pump 4 and valve 5, as Well as the elements leading from the vehicle power plant and from the drivers seat for operating such parts, are below the upper line of the chassis frame bars and thus in a large measure protected against damage.

The power shaft 3 of the motor proper extends beyond the casing 2 in both directions, and one of the bars II, here indicated at I4 is provided with a bearing 5 for the end of the power shaft 3. Thus the motor proper is to a certain extent relieved of direct torsional stresses in the operation of lifting the dump body, such stresses being largely taken care of by the bearings I5. Of course the power shaft may in the initial makeup of the motor be given any desired projection beyond the casing 2, and thus the motor, if arranged at one or the other side of the longitudinal center of the chassis on the particular vehicle, will nevertheless provide for proper bearing end support of the power shaft, and the projection of said shaft to end positions adjacent the frame bars of the chassis, as shown in Fig. 4.

The dump body I6, which ofcourse may be of any desired specific construction so far as the present invention is concerned, is pivotally connected at II to the frame bars of the chassis. The ends of the arms 'I of the power shaft 3 are connected by means of levers I8 to the underside of the dump body, preferably through a cross bar I9. The levers here shown as of double-bar formation, may be of any desired form, and the relation of the lever length to that of the arm I is such that when the arm and lever are substantially alined the dump body is at its upper lift limit.

Of course, it is apparent that by properly proportioning the lengths of the arms 'l and levers I8, the character of the lift action may be more or less controlled. Thus with the arms approximating the length of the levers, the action of the lift will gain speed at the expense of power, While with the arms shorter than the levers, power will be gained at the expense of speed. Thus by merely changing the arms and levers the dumpbody operation may be carried out speedily, if time isof importance with the particular type of dump wagon, or a proper though slower action may be had to insure handling of heavy loads, if the type of dump Wagon is for such character of loads. Thus the very installation lends itself to accommodating the motor to selectively determine the speed of the dumping operation or the power of such operation, so that a particular motor may by the position in which it is installed serve for a speedy dump-body operation or for a. particularly powerful operation, as may be required in the particular service required.

This application is a substitute for our abandoned application Serial No. 544,198, filed June 13. 1931.

What is claimed to be new is:

A dump body, a vehicle frame on which the body is swingingly supported, a rotary hydraulic motor including a shaft for the motor, levers between the ends of the shaft and the dump body for operating the dump body by rotating the shaft, and a. strut support for the motor and shaft, said strut support including transverse bars terminally connected to the frame, and longitudinal bars terminally connected to the transverse bars, said longitudinal bars including a central bar and side bars equally spaced from and on each side of the centralbar, that spacing being such as to just receive the motor and permit its application on either side of the central bar for right or left hand control by the driver, and mountings for the shaft on at least one of the longitudinal bars.
